Tests are required. Maybe you'll need to call it again. The tm6000 chip has lot of
weird behaviours. In the case of xc3028 on analog, you need to re-load the firmware
every time the stream starts. Also, it seems that tm6000 has a timeout: if the image
is not ok for a few seconds, it cuts the tuner down. So, I ended to make it to re-load
part of the firmware (the smaller part of the firmware) every time the channel changes,
when I wrote the first version of the driver. I suspect that this behavior of tuner-xc2028
were removed on the last driver reviews, to speedup tuning with all other devices that
use those chips.
